Hi,
I was wondering if it would be possible to add an argument to the aggreagte
function to retain NA by categories?(default can not to in order to avoid
breaking code) Please see below example:
df = iris
df$Species[5] = NA
aggregate(`Petal.Width` ~ Species, df, sum) # does not include NA
aggrega

Hi Florian,
just a guess, but couldn't it be that the multiplication of very small
values leads to FP underflow exceptions which have to be handled by
BLAS in a less efficient way than "normal" multiplications handled by
SIMD instructions ?
